              written notice. Each Project Manager will be responsible for (i)
              monitoring the schedules and progress of work pursuant to this
              Agreement and each SOW; (ii) receiving and submitting requests for
              information and/or assistance; (iii) determining whether a request
              he or she receives for information and/or assistance from the
              other Project Manager is necessary for the other party to complete
              a specific Deliverable; (iv) receiving and submitting
              Deliverables; (v) cooperating with the other Project Manager to
              implement acceptance testing; and (vi) supervising and recording

              agreed upon by the Project Managers to discuss the progress of the
              development effort and, if applicable, to exchange information and
              Deliverables (with such meetings expected to occur weekly via
              teleconference and bi-weekly via physical meetings in alternating

              of any such ESC Action conflict with the terms and conditions of
              this Agreement, the terms and conditions of such ESC Action will
              prevail. With the exception of interim equitable relief, neither
              party shall institute legal proceedings regarding a dispute until
              it has exercised good faith reasonable efforts to achieve
              resolution through the foregoing procedure.

              a SOW, Dorado will reasonably and in good faith consider and
              discuss the proposed change. Dorado agrees to accept any change
              proposed by Customer where Customer agrees to bear any extra
              expense to Dorado and pay (at mutually agreed time and materials
              rates) for any additional work required by such change. Any
              agreement to change a SOW shall be in writing signed by both
              party's Project Managers ("Change Order"). Notwithstanding
              anything else herein, to the extent that the terms and conditions
              of any Change Order conflict with the terms and conditions of this
              Agreement, the terms and conditions of this Agreement will
              prevail. If the parties' Project Managers cannot agree upon a
              Customer SOW change request, then either party's Project Manager
              can submit the request to the ESC for resolution in accordance
              with Section 4.2.

       4.4    Acceptance and Rejection Procedure. When Dorado has appropriately

              scheduled date for such delivery as listed in the applicable SOW).
              Customer may reject any Deliverable if such Deliverable fails in
              some material respect to meet the Specifications therefore. Each
              Deliverable shall be inspected by Customer upon delivery and will
              be deemed accepted by Customer unless written notification of
              non-compliance is sent to Dorado, defined herein, within fifteen
              (15) business days following receipt of such Deliverable by
              Customer. A written notice of rejection should provide a
              description of any such non-conformities. Upon Customer's
              rejection of any Deliverable, Dorado shall correct the
              non-conformities specified in the rejection notice within fifteen
              (15) business following receipt of such notice. When Dorado has
              made the necessary corrections to conform such a rejected
              Deliverable with the Specifications, Dorado will deliver the
              corrected Deliverable to Customer and the
              acceptance/rejection/correction provisions above shall be
              reapplied until the Deliverable is accepted by Customer; provided,
              however, that upon the third or any subsequent rejection or if the
              corrections are not made within thirty (30) calendar days of the
              initial rejection, the issue of the Deliverable's non-compliance
              shall be submitted to the ESC for resolution. If an ESC Action is
              not taken within fifteen (15) business days following such
              submission, Customer may terminate this Agreement by providing
              fifteen (15) calendar days written notice to Dorado, unless the
              Deliverable is accepted by Customer during such notice period.

       4.5.   Ownership of Deliverables. As between the parties, Customer
              exclusively shall have all right, title and interest in and to all

              specified in such SOW, at such rate Company in its sole discretion
              deems reasonable), in evidencing, perfecting, obtaining,
              maintaining, defending and enforcing Customer's Proprietary Rights
              in any Deliverables, Inventions and/or the licenses and
              assignments granted to Customer herein. Such acts may include, but
              are not limited to, execution of documents and assistance or
              cooperation in legal proceedings. If after a reasonable written
              request by Customer to Dorado, Customer is unable for any reason
              whatsoever to secure Dorado's signature to any document Customer
              is entitled to under this Section 4.6, Dorado hereby irrevocably
              designates and appoints Customer and its duly authorized officers
              and agents, as Dorado's agents and attorneys-in-fact, with full
              power of substitution, to act for and in its behalf and instead of
              Dorado, solely to execute and file any such document and to do all
              other lawfully permitted acts solely to further the purposes of
              the foregoing with the same legal force and effect as if executed

              ratifies and consents to any action consistent with the terms of
              this Agreement that would violate such Moral Rights in the absence
              of such ratification/consent. Dorado will confirm any such
              ratifications and consents from time to time as requested by
              Customer.

              the Software Products, (iii) neither Dorado's entering into nor
              performing this Agreement will violate any right of or breach any

              permissions, assignments or releases of third party rights are
              necessary to give full effect the licenses and assignments granted
              to Customer herein, for Dorado's development of the Customer
              Solution Blade, or Customer's development, production or
              distribution of any Customer Solution Blade or any other currently
              anticipated exercise of its rights hereunder.

              Deliverable (including, without limitation, the Customer Solution
              Blade as finally accepted by Customer), Related Materials and any
              modifications, derivative works or Enhancements of the foregoing
              made by Dorado, as delivered to Customer do not and will not
              infringe any third-party Proprietary Rights.

       5.3    Dorado warrants, for the benefit only of Customer, that for a

              and Deliverable shall conform in all material respects to the
              applicable Specifications for such Software Products (except for
              modifications made to any Software Product by Customer or by
              Dorado at the request of Customer) and Deliverables. Dorado
              assumes no responsibility for obsolescence of the Software
              Products.

       5.4    As the exclusive remedy of Customer for the limited warranty of
              Section 5.3, Dorado shall promptly provide modifications to
              conform such Software Products and Deliverables to the applicable
              Specifications. However, Dorado shall not be obligated to correct,
              cure, or otherwise remedy any non-conformity directly resulting
              from any (1) modification of the Software Products by Customer,
              (2) misuse or damage of the Software Products or Deliverables
              other than by Dorado employees and contractors, or (3) failure of
              Customer to notify Dorado of the existence and nature of such

       9.3    [***]

10     PROPRIETARY PROTECTION OF MATERIALS

       10.1   Confidential Information means information that each party (a
              "Disclosing Party") may, from time to time, in connection with its
              performance under this Agreement (or during the negotiation of
              this Agreement), disclose to the other party (the "Receiving
              Party") and that is marked "proprietary" or "confidential," or
              when disclosed orally the Disclosing Party notifies the Receiving
              Party in writing of its confidential nature within ten (10)
              business days of disclosure. Notwithstanding the foregoing, all
              information and materials disclosed to Dorado by Customer for use
              in the development or creation of any Deliverable or Invention and
              all information comprising or relating to any Deliverable or
              Invention shall be deemed the Confidential Information of Customer
              subject to the disclosure restrictions of this Section 10. Each
              Receiving Party agrees not to use or to disclose to any third
              party (other than for purposes contemplated by this Agreement),
              and will use reasonable efforts to prevent the disclosure to third
              parties of, any of the Disclosing Party's Confidential
              Information. Notwithstanding any provision to the contrary set
              forth in this Section 10, each Receiving Party shall have the
              right to disclose the Disclosing Party's Confidential Information
              to third-party consultants who need to know such Confidential
              Information in order to perform services as contemplated
              hereunder; provided, that such consultants have entered into
              written confidentiality and nonuse agreements, of which the
              Disclosing Party is a third-party beneficiary with rights of
              direct enforcement, with terms and conditions protecting the
              confidentiality of the Disclosing Party's Confidential Information
              that are at least as stringent as those set forth in this
              Agreement. The Receiving Party's confidentiality obligations
              hereunder shall not apply to information that the Receiving Party
              can document: (i) was in the Receiving Party's possession or known
              by it without restriction prior to receipt from the Disclosing
              Party; (ii) is or (through no fault of the Receiving Party or any
              of its employees, contractors, agents or licensees) becomes
              generally available to the public; (iii) is rightfully disclosed
              to the Receiving Party by a third party having no obligations of
              confidentiality to the Disclosing Party; provided, that the
              Receiving Party complies with any restrictions imposed by such
              third party; (iv) is independently developed by the Receiving
              Party without use of or reference to the Disclosing Party's
              Confidential Information; or (v) is required by law or regulation
              to be disclosed (including, without limitation, in connection with
              filings with the United States Securities and Exchange
              Commission); provided, that the Receiving Party uses reasonable
              efforts to restrict disclosure, to obtain confidential treatment
              therefor, and to notify the Disclosing Party of the compelled
              disclosure and to give the Disclosing Party the opportunity to
              participate in proceedings contesting such disclosure or seeking a
              protective order with respect thereto. Notwithstanding the
              foregoing, all Deliverables and Inventions developed by or for
              Dorado and designated as owned by or assigned to Customer
              hereunder shall be deemed the Confidential Information of Customer
              disclosed by Customer to Dorado, and exceptions (i) and (iv) above
              will not be applicable thereto.

       10.2   Each party acknowledges and agrees that, due to the unique nature
              of the Disclosing Party's Confidential Information, there can be
              no adequate remedy at law for any breach of its obligations under
              this Section 10, that any such breach may allow the Receiving
              Party or third parties to unfairly compete with the Disclosing
              Party, resulting in irreparable harm to the Disclosing Party, and,
              therefore, that upon any such breach or threat thereof, the
              Disclosing Party shall be entitled to seek injunctive relief and
              other appropriate equitable relief, without the necessity of
              posting any bond, in addition to whatever remedies it may have
              under this Agreement and at law, and to be indemnified by the
              Receiving Party from any loss or harm (including, without
              limitation, for attorneys' fees) in

              obligations hereunder or the unauthorized use or release of any
              Confidential Information. The Receiving Party will notify the
              Disclosing Party in writing immediately upon the occurrence of any
              such unauthorized release or other breach of which it is aware.

       10.3   Customer further agrees not to reverse assemble or reverse
              engineer the Software Products to acquire knowledge about the
              logic, structure or sequence of Software Products or decode any
              Software Products or to bypass or defeat protection methods
              provided for preventing unauthorized uses of the Software Products
              or to derive any Source Code or algorithms therefrom without prior
              written permission from Dorado.

       10.4   The provisions of this Section 10 ("Proprietary Protection of
              Materials") shall survive termination of this Agreement for any
              reason.

11     CHARGES AND PAYMENTS:

              software maintenance, and professional services as set forth in

              described in Schedule B (Statement of Work) and its referenced
              documents on a "fixed price" basis. Notwithstanding the fixed
              price nature of the service engagement, any changes to the
              requirements set forth in the SOW and related documents caused by
              a) any changes requested by Customer or necessitated by Customer's
              actions, b) any modifications to Customer's equipment and any
              associated interfaces or operating systems, or c) any failure or
              delay of Customer to provide deliverables according to the

              be considered a change and shall be subject to the change order
              process and additional charges as set forth in section 4.3 of this
              Agreement. Any failure of Customer to provide qualified personnel
              to assist Dorado as described under "resource assumptions" in
              Schedule B shall result in additional charges on a time and
              material basis.

       11.2   Customer agrees to make payments to Dorado in accordance with the
              Financials and Business Arrangements as set forth in Schedule C.
              All payments are due thirty (30) days following either the
              execution of this Agreement by both parties or a Deliverable
              Milestone Event as set forth in Schedule C as the case may be. For
              all amounts owed as a result of a Deliverable Milestone Event,
              payments shall be due thirty (30) days following the acceptance of
              such Deliverable by Customer in accordance with Section 4.

       11.3   Annual software product maintenance and support services as
              described in Schedule D shall become effective and shall be
              invoiced by Dorado upon the earlier of a) delivery of the Phase 2
              Beta Release to Customer, or b) deployment of the Customer
              Solution Blade or any of the Software Products by Customer.

       11.4   Customer agrees not to withhold payments from Dorado due to any
              provision in this Agreement, except in the event of Dorado's
              breach of the Agreement or as otherwise specifically allowed
              herein.

       11.5   Subject to Customer's prior approval of all expenses, Customer
              will reimburse Dorado for reasonable travel, lodging, and meal
              expenses and any other expenses incurred for travel to Customer's
              facilities. Dorado may elect to suspend the provision of services
              under any outstanding SOW during any period when Customer is over
              sixty (60) days past due on any amount legally owing to Dorado
              hereunder and which is not subject to a good faith dispute.

12     TAXES:

       state, municipal, or other governmental entities on any charges under
       this Agreement on the Software Products or Related Materials furnished
       hereunder or their use. Notwithstanding the foregoing, Dorado shall be

              party commits a material breach of any term hereof and fails to
              cure said breach within the 30-day period. Such notice shall set
              forth the basis of termination. (c) Upon termination of this
              Agreement due to Customer's uncured material breach of Sections
              3.1, 3.2 or 3.5, Customer shall immediately cease use of, and

              works developed therefrom granted by Customer prior to the date of
              termination, and consistent with the terms of this agreement,
              shall remain in full force and effect; and, in addition, the

              derivative works.

       14.2   ENTIRE AGREEMENT. This Agreement (together with all of the
              attached schedules and any duly executed future SOWs, which are
              all incorporated herein by reference) constitute the entire

              hereof and supersede all prior agreements, oral or written,
              relating to the subject matter of this agreement. No amendment,
              waiver or modification of any provision of this Agreement will be
              effective unless such is in writing and is executed by both
              parties hereto. The failure of either party to enforce its rights
              under this Agreement at any time for any period shall not be
              construed as a waiver of such rights.

       14.3   NO ASSIGNMENT. Neither party shall sell, transfer or assign any
              right or obligation hereunder without the prior written consent of
              the other. Any attempt to do so shall be void and shall result in
              termination of this Agreement. Notwithstanding the foregoing, in
              the case a party or all or substantially all of its assets are
              purchased by or merged into another entity, all rights and
              responsibilities under this Agreement shall transfer to the new
              controlling entity, provided that, for an assignment by Customer,
              the original intent of the resulting Customer Solution Blades
              remain materially the same. Subject to the foregoing, this
              Agreement shall inure to the benefit of and be binding upon the
              respective successors and assigns of Dorado and Customer.

       14.4   GOVERNING LAW. This Agreement shall be governed by the laws of the
              State of California without regard to its conflict of laws
              principles. In any action to enforce this Agreement the prevailing
              party will be entitled to recover its costs and reasonable
              attorneys' fees.

       14.5   SEVERABILITY. If any provision of this Agreement is held by a
              court of competent jurisdiction to be contrary to law, such
              provision shall be limited or eliminated to the minimum extent
              necessary so that this Agreement shall otherwise remain in full
              force and effect and enforceable.

              and agree that each party is an independent contractor in the

       3.7    Subject to Customer's approval prior to the provision of on-site

              herein.

       4.2    Customer agrees to make all payments to Dorado under this
              Agreement within thirty (30) days upon receipt of an invoice from
              Dorado.

              the rate of [***], or the maximum late charge permitted by
              applicable law, whichever is less, on any unpaid amount that is
              not in dispute for each calendar month (or fraction thereof) that
              such payment is overdue.

       4.4    In the event Dorado must institute legal proceedings to collect
              any amounts legally due hereunder, Customer agrees to pay the
              costs of any collection or restitution, including reasonable
              attorneys fees.

       4.5    If Customer is past due by sixty (60) days or more on any amount
              owed hereunder, Dorado may suspend its provision of maintenance
              and support services until such amount (including late payment
              charges as set forth in Section 4.4) is received by Dorado. Dorado
              may, by written notice to Customer ninety (90) days prior to the
              anniversary day, increase or decrease the annual maintenance fees
              set forth in Section 2.0. Any increase in the amount of an annual
              maintenance fee shall not exceed [***] of the previous year's fee.

       relating to this agreement.

6.0    MISCELLANEOUS

       6.1    Term and Termination. This Agreement is effective as of the date
              it is executed by the party last to sign, and subject to the terms
              hereof, remains in force until terminated. Customer may by thirty
              (30) days prior written notice terminate its maintenance service,
              releasing Dorado from the terms and conditions under Paragraphs
              3.1 through 3.8, while retaining the right to use the Software
              Products, provided the licenses for such Software Products remain
              in effect.

       6.2    Force Majeure. Should either party be unable to perform any
              obligation required of it under this Agreement other than the
              payment of money, because of any cause beyond its control
              (including, but not limited to war, insurrection, riot civil
              commotion, shortages, strike, lockout fire, earthquake, calamity,
              windstorm, flood, material shortages, failure of any suppliers,
              freight handlers, transportation vendors or like activities, or
              any other force majeure), then such party's performance of any
              such obligation shall be suspended for such period as the party is
              unable to perform such obligation.

       6.3    Entire Agreement. The provisions herein constitute the entire
              agreement between the parties with respect to the subject matter

              effective unless such is in writing and is executed by both
              parties hereto. The failure of either party to enforce its rights
              under this Agreement at any time for any period shall not be
              construed as a waiver of such rights.

       6.4    Assignment. Neither party shall sell, transfer or assign any right
              or obligation hereunder without the prior written consent of the
              other. Any attempt to do so shall be void and shall result in
              termination of this Agreement. Notwithstanding the foregoing, in
              the case a party or substantially all of its assets are purchased
              by or merged into another entity, all rights and responsibilities
              under this Agreement shall transfer to the new controlling entity.
              Subject to the foregoing, this Agreement shall inure to the
              benefit of and be binding upon the respective successors and
              assigns of Dorado and Customer.

              court of competent jurisdiction to be contrary to law, such
              provision shall be limited or eliminated to the minimum extent

                      Account Number ______________________

       This Software Escrow Agreement (the "Agreement") is made as of date of

("Depositor").

       WHEREAS Beneficiary and Depositor have entered into the miniOSS
Distribution Agreement (the "OSS Agreement") pursuant to which Depositor is to
license certain software to Beneficiary; and

       WHEREAS the OSS Agreement provides that Beneficiary and Depositor will
enter into a source code escrow agreement among themselves and an escrow agent
which provides for Depositor to deposit with, and which enables Beneficiary to
obtain from, the escrow agent certain software source code and documentation
solely for the purposes specified in the OSS Agreement;

       WHEREAS Depositor and Beneficiary desire to establish an escrow with DSI
to provide for the retention, administration and controlled access of the
deposited materials.

       WHEREAS The parties desire this Agreement to be supplementary to the OSS
Agreement pursuant to Title 11, United States [Bankruptcy] Code, Section 365(n).

       NOW, THEREFORE, for good and valuable consideration, the receipt and
adequacy of which is hereby acknowledged, and in consideration of the promises,
mutual covenants and conditions contained herein, the parties agree as follows:

ARTICLE 1  --  DEFINITIONS

       Capitalized terms not otherwise defined herein shall have the meaning set
forth in the OSS Agreement. The following definitions shall apply to the terms
set forth in this Escrow Agreement:

       1.1 "Deposit Materials" means one copy of the full source code from which
each of the Software Products and Customer Solution Blades was compiled on disk
or magnetic tape media, and all technical documentation required to allow a
reasonably skilled third party software developer to compile, understand,
prepare, replace, maintain, modify and enhance the Software Products and
Customer Solution Blades.

ARTICLE 2  --  DEPOSITS

       2.1    Obligation to Make Deposit. Within ten (10) days of the Effective
Date, Depositor shall deliver the Deposit Materials to DSI.

       2.2    Depositor's Representations. Depositor represents as follows:

              2.2.1  Depositor lawfully possesses all of the Deposit Materials
                     deposited with DSI;

              2.2.2  With respect to all of the Deposit Materials, Depositor has
                     the right and authority to grant to DSI and Beneficiary the
                     rights as provided in this Agreement;

--------------------------------------------------------------------------------
Dorado Software, Inc.           miniOSS Distribution Agreement          Page 27


<PAGE>   29

              2.2.5  The Deposit Materials are readable and useable in their
                     current form.

       2.3 Identification of Tangible Media. Prior to the delivery of the
Deposit Materials to DSI, Depositor shall conspicuously label for identification
each document, magnetic tape, disk, or other tangible media upon which the
Deposit Materials are written or stored. Additionally, Depositor shall complete
Appendix A to this Agreement by listing each such tangible media by the item
label description, the type of media and the quantity. The Appendix A must be
signed by Depositor and delivered to DSI with the Deposit Materials. Unless and
until Depositor makes the initial deposit with DSI, DSI shall have no obligation
with respect to this Agreement, except the obligation to notify the parties
regarding the status of the deposit account as required in Section 3.2 below.

       2.4 Acceptance of Deposit. When DSI receives the deposit materials and
Appendix A, DSI will conduct a deposit inspection by visually matching the
labeling of the tangible media containing the deposit materials to the item
descriptions and quantity listed on Appendix A. At the completion of the deposit
inspection, if DSI determines that the labeling of the tangible media matches
the item descriptions and quantity on Appendix A, DSI will date and sign
Appendix A and mail a copy thereof to Depositor and Beneficiary. If DSI
determines that the labeling does not match the item descriptions or quantity on
Appendix A, DSI will (i) note the discrepancies in writing on Appendix A, (ii)
date and sign Appendix A with the exceptions noted, and (iii) provide a copy of
Appendix A to Depositor and Beneficiary. DSI's acceptance of the deposit occurs
upon the signing of Appendix A by DSI.

       2.5 Verification and Testing of Deposit Materials by Beneficiary.
Beneficiary shall have the right to appoint at its expense an independent,
professional computer-programming consultant mutually agreeable to Beneficiary
and Depositor to inspect, compile, test, and review the Deposit Materials
(subject to appropriate undertakings of confidentiality and restrictions on
subsequent use or disclosure) at any time, and DSI shall permit such inspections
and testing promptly upon written request. Such inspections and testing shall be
conducted at a mutually agreed upon location. If and only if such professional
determines that the deposited Deposit Materials are incorrect or incomplete,
then Depositor shall reimburse Beneficiary for the professional's reasonable
fees and expenses and shall correct such errors or omissions in the Deposit
Materials within fifteen (15) days after notification of such errors or
omissions. Depositor shall have the option to rebut or confirm the
professional's determination.

       2.6 Deposit Updates. Unless otherwise provided by the OSS Agreement,
Depositor shall update the Deposit Materials within 60 days of release of each
Revision or New Version of the Software Products and Customer Solution Blade
which is the subject of the OSS Agreement ("Deposit Updates"). Such Deposit
Updates will be added to the existing deposit. All Deposit Updates shall be
listed on a new Appendix A and the new Appendix A shall be signed by Depositor.
Each Appendix A will be held and maintained separately within the escrow
account. An independent record will be created which will document the activity
for each Appendix A. The processing of all Deposit Updates shall be in
accordance with Sections 2.3 and 2.4 above. All references in this Agreement to
the Deposit Materials shall include the initial Deposit Materials and any
Deposit Updates.

       2.7 Removal of Deposit Materials. The Deposit Materials may be removed
and/or exchanged only on written instructions signed by Depositor and
Beneficiary, or as otherwise provided in this Agreement.

ARTICLE 3  -- CONFIDENTIALITY AND RECORD KEEPING

         3.1 Confidentiality. DSI shall maintain the Deposit Materials in a
secure, environmentally safe, locked facility which is accessible only to
authorized representatives of DSI. DSI shall have the obligation to reasonably
protect the confidentiality of the Deposit Materials. Except as provided in this
Agreement, DSI shall not disclose, transfer, make available, or use the Deposit
Materials. DSI shall not disclose the content of this Agreement to any third
party. If DSI receives a subpoena or other order of a court or other judicial
tribunal pertaining to the disclosure or release of the Deposit Materials, DSI
will

<PAGE>   30

immediately notify the parties to this Agreement. It shall be the
responsibility of Depositor and/or Beneficiary to challenge any such order;
provided, however, that DSI does not waive its rights to present its position
with respect to any such order. DSI will not be required to disobey any court or
other judicial tribunal order.

       3.2 Status Reports. DSI will issue to Depositor and Beneficiary a report
profiling the account history at least semi-annually. DSI may provide copies of
the account history pertaining to this Agreement upon the request of any party
to this Agreement.

       3.3 Audit Rights. Depositor and Beneficiary shall be entitled at
reasonable times during normal business hours and upon reasonable notice to the
DSI during the term of this Escrow Agreement to inspect the records of DSI with
respect to the Deposit Materials. Depositor and Beneficiary shall be entitled
upon reasonable notice to the DSI and during normal business hours to inspect
the facilities of the DSI with respect to the physical status and condition of
the Deposit Materials.

ARTICLE 4  --  GRANT OF RIGHTS TO DSI

       4.1 Title to Media. Depositor hereby transfers to DSI the title to the

transfer does not include the ownership of the proprietary information and
materials contained on the media such as any copyright, trade secret, patent or
other intellectual property rights.

       4.2 Right to Make Copies. DSI shall have the right to make copies of the
Deposit Materials as reasonably necessary to perform this Agreement. DSI shall
copy all copyright, nondisclosure, and other proprietary notices and titles
contained on the Deposit Materials onto any copies made by DSI. With all Deposit
Materials submitted to DSI, Depositor shall provide any and all instructions as
may be necessary to duplicate the Deposit Materials including but not limited to
the hardware and/or software needed.

       4.3 Right to Transfer Upon Release. Depositor hereby grants to DSI the
right to transfer the Deposit Materials to Beneficiary upon any release of the
Deposit Materials for use by Beneficiary in accordance with Article 5. Except
upon such a release or as otherwise provided in this Agreement, DSI shall not

ARTICLE 5  -- RELEASE OF DEPOSIT

       5.1    Release Events. As used in this Agreement, "Release Event" shall
mean any of the following:

              5.1.1  Depositor's failure to carry out obligations imposed on it
                     pursuant to the OSS Agreement or this Escrow Agreement and
                     fails to cure such breach within thirty (30) days of
                     receiving written notice of the breach from Beneficiary;

              5.1.2  Depositor becomes insolvent or becomes the subject of a
                     voluntary or involuntary petition in bankruptcy or any
                     proceeding relating to insolvency, receivership,
                     liquidation, or composition for the benefit of creditors,
                     which proceeding is not dismissed within sixty (60) days;
                     or

              5.1.3  Depositor's failure to continue to do business in the
                     ordinary course.

       5.2 Occurrence of Release Event. Upon the occurrence of one or more of
the Release Events, Beneficiary may give written notice to the DSI of the
occurrence of any such Release Event (a "Release Notice"), which notice will (i)
specify the nature of any such Release Event, and (ii) instruct DSI to deliver
the Deposit Materials to Beneficiary at a time specified by Beneficiary (but not
earlier than ten

(10) working days after the Release Notice is sent by DSI to Depositor). Upon
receipt of a Release Notice, DSI shall immediately transmit a copy of the
Release Notice to Depositor by certified mail, return receipt requested, or by
commercial express mail. If, within ten (10) working days after DSI transmits
the Release Notice to Depositor, Depositor fails to notify DSI in writing that
Depositor disputes the Release Notice, DSI shall immediately deliver the Deposit
Materials to Beneficiary in accordance with the instructions of Beneficiary
contained in such Release Notice.

       5.3 Dispute of Occurrence of Release Event. If Depositor disputes
Beneficiary's Release Notice, then within ten (10) working days of the date DSI
sent the Release Notice, Depositor must file concurrently with DSI and
Beneficiary a written notice executed by an authorized representative of
Depositor stating that no Release Event has occurred or that the Release Event
no longer exists, and specifying the facts in support of its position. If
Depositor fails to file such a written notice, then the DSI shall deliver the
Deposit Materials to Beneficiary in accordance with the instructions of
Beneficiary. If Depositor files a written notice disputing Beneficiary's claim
that a Release Event has occurred, then the DSI shall not deliver the Deposit
Materials to either Beneficiary or Depositor until directed to do so by
Depositor and Beneficiary jointly or by an arbitrator, or until the DSI receives
from Beneficiary a certified copy of a final order of an arbitrator or a court
of competent jurisdiction determining that a Release Event has occurred
entitling Beneficiary to receive delivery of the Deposit Materials.

       5.4 Grant of License upon Release of Deposit Materials. Upon release of
the Deposit Materials in accordance with this Article 5, Beneficiary is granted
a fully-paid, royalty free, personal, non-exclusive and non-transferable (except
as set forth in Section 10.7) license to reproduce, modify and otherwise use the
Deposit Materials to maintain and support the Dorado Software Products and
Customer Solution Blades. Beneficiary shall be obligated to maintain the
confidentiality of the released Deposit Materials.

ARTICLE 6  -- ARBITRATION

       6.1    Arbitration of Dispute over Occurrence of Release Event

              6.1.1 Arbitration Procedure. If (i) Beneficiary receives a written
       notice from Depositor stating that no Release Event has occurred or that
       the Release Event no longer exists, and if Beneficiary desires to obtain
       a release of the Deposit Materials as a result of the Release Event(s) in
       dispute, or (ii) the DSI receives a Release Notice and the DSI is
       uncertain whether the Release Notice was timely or otherwise effective,
       Beneficiary or DSI shall file a demand for binding arbitration with the
       American Arbitration Association ("AAA") in Santa Clara County. Any such
       arbitration shall take place in Santa Clara County and be conducted by a
       single arbitrator according to the then current Commercial Rules of the
       AAA. Judgment upon the award rendered by the arbitrator may be entered in
       any court having jurisdiction thereof. 6.1.2 Scope of Arbitration. The
       sole issue to be decided in an arbitration over the occurrence of a
       Release Event shall be whether a Release Event existed at the time
       Beneficiary gave notice to the DSI of such Release Event. The decision of
       the arbitrator shall be in writing and made within thirty (30) days
       following the conclusion of any evidentiary hearing. The arbitrator shall
       have no power or authority to modify the agreements of the parties. The
       arbitrator shall have no authority to award damages or to enter any form
       of injunctive relief.

              6.1.2 Scope of Arbitration. The sole issue to be decided in an
       arbitration over the occurrence of a Release Event shall be whether a
       Release Event existed at the time Beneficiary gave notice to the DSI of
       such Release Event. The decision of the arbitrator shall be in writing
       and made within thirty (30) days following the conclusion of any
       evidentiary hearing. The arbitrator shall have no power or authority to
       modify the agreements of the parties. The arbitrator shall have no
       authority to award damages or to enter any form of injunctive relief.

              6.1.3 Arbitration Expenses. If the arbitrator determines that a
       Release Event existed at the time Beneficiary gave notice to DSI of such
       Release Event and such Release Event still existed at the time of
       Depositor's filing of a written notice disputing the existence of such
       Release Event, Depositor shall pay all fees and costs incurred in
       connection with such arbitration. If the arbitrator determines that a
       Release Event did not exist at the time Beneficiary gave a Release Notice
       to DSI of such Release Event, Beneficiary shall pay all fees and costs
       incurred in connection with such arbitration. Such fees and costs may
       include, without limitation, the



--------------------------------------------------------------------------------
Dorado Software, Inc.           miniOSS Distribution Agreement          Page 30


<PAGE>   32

       reasonable attorney's fees and costs incurred by the prevailing party and
       DSI's fees (if any) in connection with the arbitration proceeding.

       6.2 Arbitration of Other Disputes. Any other dispute relating to or
arising from this Agreement shall be resolved by arbitration (separate from any
arbitration over the occurrence of a Release Event) under the then current
Commercial Rules of the AAA. The arbitration shall take place in Santa Clara
County, California. Any court having jurisdiction over the matter may enter
judgment on the award of the arbitrator(s). Service of a petition to confirm the
arbitration award may be made by first class mail or by commercial express mail,
to the attorney for the party or, if not represented, to the party at the last
known business address. The prevailing party(ies) shall be entitled to an award
of costs and reasonable attorneys' fees.

       6.3 Notice of Requested Order. If any party intends to obtain an order
from the arbitrator or any court of competent jurisdiction which may direct DSI
to take, or refrain from taking any action, that party shall (i) give DSI at
least two business days' prior notice of the hearing, (ii) include in any such
order that, as a precondition to DSI's obligation, DSI be paid in full for any
past due fees and be paid for the reasonable value of the services to be
rendered pursuant to such order, and (iii) ensure that DSI not be required to
deliver the original (as opposed to a copy) of the Deposit Materials if DSI may
need to retain the original in its possession to fulfill any of its other
duties.

ARTICLE 7  --  TERM AND TERMINATION

       7.1 Term of Agreement. The initial term of this Agreement is for a period
of one year. Thereafter, this Agreement shall automatically renew from
year-to-year unless (i) Depositor and Beneficiary jointly instruct DSI in
writing that the Agreement is terminated; or (ii) the Agreement is terminated by
DSI for nonpayment in accordance with Section 7.2. If the Deposit Materials are
subject to another escrow agreement with DSI, DSI reserves the right, after the
initial one year term, to adjust the anniversary date of this Agreement to match
the then prevailing anniversary date of such other escrow arrangements.

       7.2 Termination for Nonpayment. In the event of the nonpayment of fees
owed to DSI, DSI shall provide written notice of delinquency to all parties to
this Agreement. Any party to this Agreement shall have the right to make the
payment to DSI to cure the default. If the past due payment is not received in
full by DSI within one (1) month of the date of such notice, then DSI shall have
the right to terminate this Agreement at any time thereafter by sending written
notice of termination to all parties. DSI shall have no obligation to take any
action under this Agreement so long as any payment due to DSI remains unpaid.

       7.3 Disposition of Deposit Materials Upon Termination. Upon termination
of this Agreement by joint instruction of Depositor and Beneficiary, DSI shall
destroy, return, or otherwise deliver the Deposit Materials in accordance with
Depositor's instructions. Upon termination for nonpayment, DSI may, at its sole
discretion, destroy the Deposit Materials or return them to Depositor. DSI shall
have no obligation to return or destroy the Deposit Materials if the Deposit
Materials are subject to another escrow agreement with DSI.

       7.4 Survival of Terms Following Termination. Upon termination of this
Agreement, the following provisions of this Agreement shall survive: Section 2.2
("Depositor's Representations"), Section 3.1 ("Confidentiality"), Section 4.3
("Right to Transfer Upon Release"), Section 5.4 ("Right to Use Following
Release" if a release of the Deposit Materials has occurred prior to
termination), Article 8 ("DSI Fees") and any provisions in this Agreement which
specifically state they survive the termination or expiration of this Agreement.

ARTICLE 8  --  DSI FEES

       8.1 Fee Schedule. DSI is entitled to be paid its standard fees and
expenses applicable to the services provided. Beneficiary shall be responsible
for payment of DSI's fees. DSI shall notify Beneficiary at least 90 days prior
to any increase in fees. For any service not listed on DSI's standard fee
schedule, DSI will provide a quote prior to rendering the service, if requested.

       8.2 Payment Terms. DSI shall not be required to perform any service
unless the payment for such service and any outstanding balances owed to DSI are
paid in full. Fees are due upon receipt of a signed contract or receipt of the
Deposit Materials whichever is earliest. If invoiced fees are not paid, DSI may
terminate this Agreement in accordance with Section 7.2. Late fees on past due
amounts shall accrue interest at the rate of one and one-half percent per month
(18% per annum) from the date of the invoice.

ARTICLE 9  --  LIABILITY

       9.1 Right to Rely on Instructions. DSI may act in reliance upon any
instruction, instrument, or signature reasonably believed by DSI to be genuine.
DSI may assume that any employee of a party to this Agreement who gives any
written notice, request, or instruction has the authority to do so. DSI shall
not be responsible for failure to act as a result of causes beyond the
reasonable control of DSI.

       9.2 Indemnification. DSI shall be responsible to perform its obligations
under this Agreement and to act in a reasonable and prudent manner with regard
to this escrow arrangement. Depositor and Beneficiary each agree to indemnify,
defend and hold harmless DSI from any and all claims, actions, damages,
arbitration fees and expenses, costs, attorney's fees and other liabilities
incurred by DSI relating in any way to this Escrow Agreement provided that (i)
DSI has acted in the manner stated in the preceding sentence, (ii) DSI promptly
gives Depositor and Beneficiary notice of any such claim or action; (iii)
Depositor and Beneficiary shall have joint authority to select defense counsel
and to control the defense and settlement of such claim; and (iv) DSI cooperates
as reasonably requested in such defense.

ARTICLE 10  --  GENERAL PROVISIONS

       10.1 Controlling Law. This Agreement is to be governed and construed in
accordance with the laws of the State of California, without regard to its
conflict of law provisions.

       10.2 Supplementary Agreement. The parties agree and acknowledge that this
Escrow Agreement is, and is intended to be, supplementary to the license
contained in the OSS Agreement, as the term "supplementary" is used in 11
U.S.C.ss. 365(n).

       10.3 Entire Agreement. This Agreement embodies the entire understanding
among the parties with respect to its subject matter and supersedes all previous
communications, representations or understandings, either oral or written. DSI
is not a party to the OSS Agreement between Depositor and Beneficiary and has no
knowledge of any of the terms or provisions of any such OSS Agreement. DSI's
only obligations to Depositor or Beneficiary are as set forth in this Agreement.
No amendment or modification of this Agreement shall be valid or binding unless
signed by all the parties hereto, except that the Beneficiary need not sign
Appendix A.

       10.4 Waiver. The failure of any party hereto to require performance by
another party of any provision hereof shall not affect the full right to require
such performance at any time thereafter nor shall the waiver of any party of a
breach of any provision hereof by any other party be taken or held to be a
waiver of the provision itself.

       10.5 Notices. Any notice required or permitted to be given by either
party under this Agreement shall be in writing and shall be sent by express
carrier to the other party at the address first set
